What IS activation energy, really?
What is activation energy in chemistry? Where does it come from and why is it so important? Using 3D animations, we look at what gives reactions a high or low activation energy and why it is so important to reaction rates. Along the way, we look at examples, like the science of explosives and rocket fuels.

‘Ignition’ by John D Clark - I was going to post a link to a free resource but it appears the book is back in print. Since I’m not sure if the legal status of free links has changed, I’ll leave it to you to google it and do the right thing.

How Do Chemical Reactions REALLY Happen?
Переглядів 44 тис.3 місяці тому
How do chemical reactions actually take place and what is chemical kinetics? With animations, we look at the chemistry and science of how reactions work, including: the exact moment two molecules meet, the kinetic theory of gases, why kinetics is all about probabilities, what the differences are between gas- and solution-phase reactions, and why solid phase reactions are so different (hint: it’...

What is molecular orbital theory and how does it work? Are you confused about frontier orbitals, HOMO and LUMOs? These essential concepts in chemistry and science are explained with examples and 3D animations. How three oxygen atoms come together to make ozone: butane.chem.uiuc.edu/pshapley/genchem2/a7/2.html For a detailed academic lesson on molecular orbital theory, I recommend Chad’s Prep: u...

Where were you when I was in quantum physics courses in my university years? 30 years later, and now I get it! Thank you.
Normal people : Orbital My chemistry teacher: whore-bit-taal
I colleague of mine made the same mistake and got some potassium hydroxide into his face. He wore his goggles and immediately washed it off so nothing serious happened
Then what is smoldering ?
I sure like your accent! - Thanks for a great video.
@4:07 can we use centigrade and degree together? Very nice lecture please upload some on thermodynamics and chemical bonding from basic to advance because those two really bother me.
I was looking for waldo
I mean how could i've missed such high quality content. BRAVO! Outstanding work and passion.
In High School shop class, the instructor had several sample of beryllium/copper alloy, known in the US as beryllium-bronze. It was common in small instruments as springs or electrical contacts. The color of the alloy is very distinctive. Teacher had lost part of a finger due to a sliver of beryl-bronze under his fingernail.
is orbital a wave
Shoutout to all the people who are here after watching Andrew Hall on Thunderbolt Project. 😳
The place where people are likely to pass is an awesome explanation. Thanks
I don’t usually like when educational UA-cam tries to be funny, or when funny people try to make educational content. But I honestly laughed so hard when you busted out the champagne. Well played, sir. And great follow up with Goodwin
Is there a mathemstical method to calculate the amount of energy [eV] of each subshell (s, p, d, f) per shell (n=1,…,7) of an atom in the periodic table of chemical elements; and thus calculating theirs absorbion and emission spectra?
brither can u make a seperate video on how waves lookline in a sperical form ?thats the only thing i still dont get
Love this!
Well explained, I’m a little closer thanks
how can the amount of energy for each sublevel (s,p,d,f) per shell (1,...,7) be calculated?
Beryllium is terrifically stiff, making it useful for such things as (at one point) Formula One brake calipers.
For those of you who are wondering, second place is "silicon" at 28%. The ready abundance is part of the reason why the revolution of silicone construction materials is so vital to our modern world.
captain obvious?
Does iodine form crystals?
OK but question how the hell do you know that it was 13.7 billion years ago how the hell do you know that
Yes please
❤😂😅😅
Isn’t the uncertainty of the Avogadro number the same as the uncertainty of the gas constant in the ideal gas equation?
Quantum particles are always spread across spacetime because of the uncertainty principle. I understand that hydrogen can do this too. Does this mean that hydrogen can be found orbiting in cloud around another atom?
In theory, everything's a quantum particle. The difference between an electron and a hydrogen atom is that as the momentum increases, the uncertainty of its position gets reduced to the point where it's mostly insignificant. So you *could* find a hydrogen atom suddenly appearing in a totally different electron cloud but a) a straight 'teleportation' style tunnelling is incredibly unlikely, and b) it would be difficult to tell it apart from straightforward proton transfer of the kind we regularly find in acid-base reactions.
Oxygen right on the corner 🗿
厉害,终于在比较底层的原理上理解了火焰的燃烧,包括气体(液体)、固体的燃烧。
Nice job
Oxygen does not stay in an elemental form for long ..🌬️💨..So it is a good indicator of life, if found on an Alien 👽👾 world 🌍
3:19 that looks like a red cell
No. I aint doing allat. Like this may happen, but just... no. I cant do it Oh yeah also P4O10 is real Yeah what the flourine.
7th is best (for me)
Is the abundance stat by numberbof oxygen atoms or mass? Only because doesn't iron make up more of the earth's mass or am i wrong? Good video btw
It's by atoms because this is a chemistry channel. 👍
Ive got a knowlegdgegasm from this explanation of orbitals. I feel like i am genius right now. 8 years i have spent trying to understand this.❤
My HS chem teacher actually used to talk about "little boy atoms and little girl atoms"....
This is why life after the first bacteria and algae produced oxygen it needed ~ 1 or 2 billion years until there was enough free oxygen in the water (and later in the air) for animals to be able to breathe. First all the stones had to be oxygenated ;-)
three bonding orbitals...is this something to do with Hybridization of sp orbitals SP3 and SP2
Yes, but we take it further so that all the orbitals of all the atoms overlap. Check out my video on Molecular Orbitals for details (it's in the description).
My wife, Kate, is silly. She's a breath of fresh air.
Electrons in phase and out of phase is exactly the question I had looking for this video
So this could all be bullshit as it is still just a theory
'Theories' in science are robust models that explain observed behaviour. They are always updated and, on occasion replaced, but by the time they are accepted as a 'theory' rather than a 'hypothesis', they at least work and are no longer bullshit.
Otherwise this was nice and great
I need more explanation on characteristics of orbitals
Orbital = a space near the nucleus where we are likely to find an electron.
Are you hawe fals! oxigén is from óceán!the trable is ,20.93% mérve Time befor!
The second best element is Silicone
Thanks, I'd been wondering about this..
what are subshells? I have always just got to know that orbitals are madeup of subshells but what are these s,p,d,f subshells ?
